4. A system comprising blocks, a light frictionless pulley (neglect its mass and there if no friction between the pulley and the rope), and connecting ropes is shown in the figure. The 9.0-kg block accelerates downward when the system is released from rest. You can ignore the friction between the block and the incline plane. 6.0 kg 30 4.0 kgp 9.0 kg a) Draw a free body diagram and write Newton's second law for the 6.0 kg mass. b) Draw a free body diagram and write Newton's second law for the 4.0 kg mass. c) Draw a free body diagram and write Newton's second law for the 9.0 kg mass. d) Calculate the acceleration of the system. e) Calculate the tension in the rope between the 6.0 kg and 4.0 kg masses. f) Calculate the tension in the rope between the 4.0 kg and 9.0 kg masses.
